A macro to create a signal, like perseus's MakeRx

[huang12zheng]

show code:

• input

#[derive(Serialize, Deserialize, ReactiveState)]
#[rx(alias = "AppStateRx")]
pub struct AppState {
    /// Authentication data accessible to all pages.
    #[rx(nested)]
    pub auth: RxVec<AuthData>,
}

• output:

#[derive(Clone)]
pub struct AppStatePerseusRxIntermediate {
    pub auth: <RxVec<AuthData> as ::perseus::state::MakeRx>::Rx,
}

impl From<AppState> for AppStatePerseusRxIntermediate {
    fn from(value: AppState) -> AppStatePerseusRxIntermediate {
        use ::perseus::state::MakeRx;
        value.make_rx()
    }
}

impl ::perseus::state::MakeRx for AppState {
    type Rx = AppStatePerseusRxIntermediate;
    #[cfg(debug_assertions)]
    const HSR_IGNORE: bool = false;
    fn make_rx(self) -> Self::Rx {
        use ::perseus::state::MakeRx;
        Self::Rx {
            auth: self.auth.make_rx(),
        }
    }
}
...
>> and there are things like RxVec or RxHashMap.

I can just add a macro and go from the basic schema to leptos signal. What do you think of this idea?

Yes, I think this kind of wrapper is very convenient. I have wondered what the best way is to replicate something like Solid's "stores" (which give reactive access to deeply-nested form fields) and this is certainly one approach.
